N. Deceitful social technique used by nubile young twenty-somethings to introduce potential suitors to their friends.

This technique involves an attractive woman hitting on a man. She is the lure, dangling in front of the prey. When the man is significantly invested in the conversation, the woman introduces her friend with the glandular problems and lazy-eye(s). The attractive woman (the bait) disappears and the switch is complete.

Poor Steve found himself a rocket, but she pulled the ol' bait n' switch on him and now he's stuck over there with that tugboat friend of hers.
